InferAddressSpaces: Replace undef with poison in tests (#130083)

2025-03-06T16:20:46+00:00

[InferAddressSpaces] collect flat address expression from return value (#70610)

2023-11-01T05:32:38+00:00

If function return value's type is pointer, we can try to collect flat
address expression from it.
This PR also fixes noop_ptrint_pair_ce2 in noop-ptrint-pair.ll in #70611

[ConstExpr] Remove select constant expression

2023-03-16T09:32:08+00:00

This removes the select constant expression, as part of
https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179.
Uses of this expressions have already been removed in advance,
so this just removes related infrastructure and updates tests.

InferAddressSpaces: Convert tests to opaque pointers

2022-11-28T01:26:16+00:00

Had constantexprs be mangled by the opaquify script; had to update
those lines manually:
  NVPTX/bug31948.ll
  AMDGPU/old-pass-regressions.ll
  AMDGPU/old-pass-regressions-inseltpoison.ll
  AMDGPU/infer-address-space.ll

Required re-reunning update_test_checks:
  AMDGPU/redundant-addrspacecast.ll

In AMDGPU/insert-pos-assert.ll, bitcast_insert_pos_assert_2 deleted a
getelementptr of 0 which I'm guessing was relevant. Replaced with an
offset 1 GEP to ensure another addrspacecast is inserted.

AMDGPU/infer-getelementptr.ll had one case improve by introducing an
inbounds.

Recommit "[InstSimplify] Remove select ?, undef, X -> X and select ?, X, undef -> X transforms" and its follow up patches

2020-08-12T17:45:27+00:00

This recommits the following patches now that D85684 has landed

1cf6f210a2e [IR] Disable select ? C : undef -> C fold in ConstantFoldSelectInstruction unless we know C isn't poison.
469da663f2d [InstSimplify] Re-enable select ?, undef, X -> X transform when X is provably not poison
122b0640fc9 [InstSimplify] Don't fold vectors of partial undef in SimplifySelectInst if the non-undef element value might produce poison
ac0af12ed2f [InstSimplify] Add test cases for opportunities to fold select ?, X, undef -> X when we can prove X isn't poison
9b1e95329af [InstSimplify] Remove select ?, undef, X -> X and select ?, X, undef -> X transforms

Revert "[InstSimplify] Remove select ?, undef, X -> X and select ?, X, undef -> X transforms" and subsequent patches

2020-07-16T05:02:33+00:00

This reverts most of the following patches due to reports of miscompiles.
I've left the added test cases with comments updated to be FIXMEs.

1cf6f210a2e [IR] Disable select ? C : undef -> C fold in ConstantFoldSelectInstruction unless we know C isn't poison.
469da663f2d [InstSimplify] Re-enable select ?, undef, X -> X transform when X is provably not poison

[IR] Disable select ? C : undef -> C fold in ConstantFoldSelectInstruction unless we know C isn't poison.

This matches the recent change to InstSimplify from D83440.

InferAddressSpaces: Fix cloning original addrspacecast

2019-06-17T14:13:29+00:00

If an addrspacecast needed to be inserted again, this was creating a
clone of the original cast for each user. Just use the original, which
also saves losing the value name.

llvm-svn: 363562

Revert "Temporarily Revert "Add basic loop fusion pass.""

2019-04-17T04:52:47+00:00

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.
